15 Claims.

This invention relates to the application of cement to shoe parts and isherein illustrated as embodied in a machine for coating the peripheralportion of an unattached moccasin toe piece.

In the mocassin type of shoe it is desirable to have a well dened ridgerunning around the toe and in practice this is accomplished by bevelingthe upper and the toe piece, turning the beveled portion of the toepiece outwardly to form a ange, and joining the beveled edges face toface by a heavy line of stitching. Since the beveled edges of the upperand toe piece are rather abrupt and narrow, it is desirable to join themwith cement to facilitate the stitching operation and to eliminategapping at the seams due to the relaxation of the stitching and leatherafter the shoe has been worn a while.

'I'he object of the present invention is, therefore, to provide animproved machine for applying cement to the out-turned beveled flange ofa moccassin toe piece Without smearing the display surface, theillustrated machine being of the automatic type in that the work whenplaced in the machine is self-guiding and the design being such that itis rapid and efcient in operation.

In accordance with the aforesaid object, one feature of the presentinvention resides in the provision of coacting feeding means forgripping the flanged portion of the toe piece and moving it lengthwisethrough the machine, the toe piece being guided to turn in its own planeso that the ange moves in a substantially linear path during part of itsmovement. This is effected by the combined action of the aforesaidfeeding means and a member arranged to bear against the flanged portionof the toe piece, whereby one of the feeding means which is suppliedwith cement coats the entire peripheral ange of the toe piece.

During the feeding movement there is a tendating feed rolls and guidesnecessary to accomplish peripheral movement of the toe piece;

Fig. 3 shows a front elevation of the feed rolls and guide with the toepiece shown in dotted lines;

Fig. 4 is an enlarged fragmentary view of the feed rolls gripping theilanged portion of the toe piece; and Y Fig. 5 is a fragment of the toepiece showing the beveled edge E before and after bending.

The toe piece TP (Fig. 5) is provided with a flange E the flesh surfaceof which is beveled at e. Preparatory to the application of cement tothe beveled surface e (Fig. 5), the ange E is premolded so that it isbent back at substantially right angles to the body of the toe Piece TP.Referring to Figs. 3 and 4, the bent back beveled flange E of the toepiece TP is shown presented to a pair of coacting feed rolls I0 and I2constructed and arranged to grip the grain and fleshsides respectivelyof the flange and to move it lengthwise, the piece being caused to turnin its own plane by the combined action of the rolls I0 and i2 and anabutment I4 arranged to bear against the flange and being held fromlateral movement between the rolls by a guide roll I5.

The rolls lll and I2 are mounted on a pair of shafts I8 and 20 whichrotate in opposite directions so as to feed the work from right to left,as viewed in Fig. 3. The shafts I8 and 20 are mounted in the frame A ofa machine of the type shown in Letters Patent of the United States No.1,851,162, granted March 12, 1932, upon an application of J. W.Cosgrove, to which reference may be had for a description of those partsnot herein more fully shown and described.

The lower shaft I8 upon which the roll I0 is mounted is journaled on anarm 22 pivoted on the frame A, the roll Iii being yieldably held by aspring (not shown) which urges the roll I0 against the work or toalimiting'position short yof the roll I2 determined by 'a stop screw 24,the

position of the stop screw being 'adjustable by the hand wheel 25. f

In the present instance the roll Ill is provided with a frustoconicalsurface in order to hold the flange E of the toe piece in such aposition that the beveled flesh side e of the flange will lie in ahorizontal plane, thereby facilitating the application of cement to thatsurface.

" The cement `applying roll I2v has aknurled surface and is mounted inco-operative relation with the roll Il), and, in accordance with thedisclosure of the aforesaid Patent No. 1,851,162,

it is supplied with a uniform coating of cement by a roll 26 whichtransfers cement from a pickup roll 28 to the roll I2. The pick-up roll28 dips in a cement pan 30 and is provided with an adjustable stripperor doctor roll 32 by which the quantity of cement transferred by theroll 28 to the roll 25 is governed.

In the present invention the grip afforded by the rolls I and I2 willnot alone hold the toe piece suiliciently to provide a continuous feedas there is a tendency for the rolls to squeeze the toe piece laterallyof the rolls and as a result the piece will run oli of the rolls beforethe entire flange has been coated unless it is held and guided by hand.It is not satisfactory tov guide the piece by hand, since that requiresthe close attention of the operator, and so the machine is provided witha roll I6 arranged to engage the body of the toe piece below the top ofthe roll I 0, as shown in Fig. 2, and on the vertical diametertherethrough to hold the piece firmly against the end face of the rollI0. The roll I6 is rotatably mounted on an approximately vertical axisso that its surface rolls along the work in the direction of movement ofthe same, the axle of the roll being journaled in the lower end of anarm 34 which is pivotally suspended at its opposite end from a yoke 35.The yoke is provided with a spindle 3S which is adjustably held in asplit clamp 49 formed at the end of a pedestal 42, the latter beingsecured at its other end to the pivoted arm 22. Artooth 44 (Fig. 2)depends from the yoke 36 and forms a stop for a limit pin 4S adjustablythreaded through the arm 34 for preventingv contact between the rolls I0 and I6 when there is no work in the machine. A tension spring 48,secured at its ends to the arm 34 and the pedestal 42, yieldably urgesthe roll I6 toward the end face of the roll II).

The forces applied to the beveled flange E of the toe piece by therotating rolls I0 and I2 and by the roll I6 are such as to cause the toepiece to rotate about a horizontal axis rather than to travel more orless linearly around the peripheral edge of the toe piece. In order,therefore, to overcome this rotational tendency and to provide asubstantially automatic traverse around the periphery of the piece, anabutment I4 is arranged to engage the toe piece at a point to one sideof thev bite of the rolls I0 and I2 and slightly above this point. Theexact location of the abutment must be chosen carefully so that it willhold the side runs of the toe piece in a substantially horizontal plane(Fig. 3) during the traverse of that portion of the piece and yet willpermit the whole piece to rotate about a horizontal axis as it traversesthe toe piece from one side run to the other. The abutment I 4 ismounted in the chosen position and extends transversely of the rolls i0and I2. It is fixed to a vertical plate 58 the surface of which isparallel to and substantially in the plane of the inner lateral face ofthe roll I0. The lower portion of the plate occupies a slot 49 formed inthe end of a plate 5I adjustably mounted on the pivoted arm 22 of themachine. The head of a screw 52 threaded into the plate I locks theplate 50 in the slot. The inner surface of the plate forms an edge gagefor theA edge of the turned-out flange E.

As indicated in Fig. 3, the work moves in the direction of the arrow,the rolls I0 and I2 constantly' advancing the work from right to left ina substantially linear path while the abutment I4 contacts theperipheral ange of the work prior to its passage between the rolls I0and I2 and holds it from counterclockwise rotation about a horizontalaxis during the traverse of the straight runs and permits rotation ofthe toe piece at the curved run around the toe. The work is introducedat the beginning of a straight run, as indicated in Fig. 3, with thegrain surface in contact with the periphery and the end face of the rollI0, the edge of the beveled flange abutting the surface of the plate 50.It is evident that the position of the grain surface, that is, facingaway from the cementing roll, is such that the liability for the cementto gain access to this surface is minimized. The rotation of the rollsautomatically traverses the piece without manipulation by the operator,thereby coating the toe piece rapidly and efficiently.
